How To - Repack A Silencer For Your ATV Or Motorcycle

RM YouTube Channel

Details

    FMF’s Power Core IV S/A Silencer aims to give your motorcycle, UTV, or ATV a near perfect balance of price, durability, and performance that won’t leave you wanting anything else. Cues for performance were taken from FMF’s top of the line exhaust systems for a solid boost to both horsepower and torque. And with that power you still have the option to run either a USFS approved spark arrestor or optional 96db quiet core.

    The aluminum body also promotes performance and quiet operation thanks to the ample room for packing material that extends the period between repacking / servicing. With the Power Core IV S/A being rounded off with quality construction, great looks, and interchangeable inserts, this silencer is near the top of the list when you're looking for aftermarket exhaust.

    Specs:
  • Aftermarket silencer for your 4 stroke
  • Comes with USFS approved spark arrestor installed
  • Increase in horsepower and torque over stock
  • Durable stainless steel end cap and mid pipe
  • Lightweight aluminum oval canister
  • Lower weight compared to stock exhaust
  • Easily disassembled for maintenance
  • Advanced packing material extends life
  • Optional 96dB quiet insert available
  • Champagne color anodized canister

FMF Honda XR 200 pipe.
Just what I wanted, fits like a glove. What really blows my mind though is how I always get what I order from Rocky Mountain the day after I order it. Always! Amazing, they're faster than Amazon.

OMG...MORE POWER
OMG...MORE POWER!!!!!! What a major improvement. I was skeptical at first, but oh boy does it work!!! FMF is a little bit quieter that the stock 230 muffler with the baffle removed, but allows the little engine to breathe SO much better (especially after re jetting the carb).
My only complaint was a small scratch in the muffler case, but the plastics cover it up so I can't even see it. All said and done...FMF and Rocky Mountain friggin' ROCK!!!

If your buying for the 06 and newer crf250r does it come with 2 pipes?
A shopper on Sep 19, 2016
BEST ANSWER: No, it's just a single pipe.
Does the spark arrestor make the sound less strong?
Jérôme G on Dec 28, 2017
BEST ANSWER: Not really. Its just a small cone shaped screen. To me it seemed just a tad less noisy at idle but about same when hard on the gas. Mine was a bit less noisy than a earlier version of same exhaust though.
Does this Silencer connect to the stock header?
A shopper on May 23, 2017
BEST ANSWER: Yes it does you'll just need some heat temp silicone which isn't supplied but suggested in the instructions
does this muffler assembly come with a new exhaust donut/gasket? or do I need to purchase a new one
DANIEL W on Apr 5, 2017
BEST ANSWER: It's been over a year since I installed. To my recollection, it was the muffler only. I would reach out to FMF directly or the distributor. Sorry I couldn't have been more help.
has any body put the the fmf 4 on a klx 450 r ? any jetting tips
Brad T on Nov 13, 2016
BEST ANSWER: Brad, we have not mounted the FMF on the KLX. but have had very good results on the DR 650 and the Husaberg FE 450. We added a bigger Mikuni on the 650 and used stock jetting, the Husaberg is injected so NA there. The weight savings on both is a big plus especially the DR650 POUNDS SAVED! Great sound, better throttle response on both throughout power band.
My son installed this new FMF exhaust and didn't tighten the bolts before he went for a quick ride. He's now list the bolt that attached the exhaust to the frame just below the seat. What size should that be?
Aaron K on Jan 13, 2018
BEST ANSWER: Need year, make, model of the machine. Probably fastest to just take another one of the same size off the machine that fits the hole and take it to a hardware store and match it up.
Does it come with new muffler clamp that conects the two pipes Together or is this the whole system?
Kenny D on Jun 29, 2017
BEST ANSWER: This is a slip on silencer (muffler), Slips on to your stock header pipe, it does come with the clamp and all hardware to bolt on to your bike
Does this fit the fmf power bomb because I have this and the fmf power bomb and it doesn't slip on?
Austin H on Mar 22, 2018
BEST ANSWER: I use the powerbomb header and FMF powercore 4 silencer on an XR650L with no problems
Will I need to rejet a 2007 TTR 230 if I add this ?
John B on Dec 5, 2017
BEST ANSWER: It was installed on the 24th, ran just fine, no need to rejet ! GREAT PRODUCT !
Does this come with the gasket that goes between the head pipe and muffler? I have a 2009 Honda Crf450r.
Joshua A on Feb 15, 2017
BEST ANSWER: If it's needed it will. If not then you just put it together with heat temp silicone as stated in the instructions it comes with
What the difference between the FMF Power core IV and FMF Q4? Is there a real noticeable difference? Does one flow or perform better than the other? Or are they 6s? Riding 2008 KLX450R.
Brett S on Mar 20, 2018
BEST ANSWER: The power core IV is designed to give your machine more power throughout a certain RPM range (usually it's a wider mid range) The Q series is designed to quiet your machine down. It might show the results on a dyno but personally unless you're all out racing on a track I don't think you'll notice any difference. Now that I'm older and have tinnitus from loud noises I personally recommend the quiet ones so you're not being obnoxious and causing someone else deafness. If you're still in doubt call Donny Emler at FMF. He's a great guy and a wealth of knowledge. He used to help me back in my racing days. Good luck.
This fmf powercore 4 exhaust for a warrior 350 come with quite core and spark arrestor ??
Joshua O on Nov 13, 2017
BEST ANSWER: Yes on both, but keep in mind it will be louder than stock.
Does this pipe come with a header pipe and if not does it fit on my stock header? 1999 wr 400f
A shopper on Jan 23, 2017
BEST ANSWER: Bought this for a 2004 yamaha raptor 350. The fit was perfect to the stock header. It did not come with a header pipe. Great sound and a little seat of the pants power..
Looking to put this on a 2013 wr250f. It lists part #1047000101. Talking with my mechanic, he says after looking in his catalog the pipe should hexagonal or flat sided. Is this an option with this pipe, different part number?
Greg D on May 29, 2018

I own a 2009 Honda CRF 450R. Will this silencer slip on to my existing factory pipe? Is reprogramming the ECU required for the engine to run properly, or is it just optional for better performance? Thanks!
Cole B on Sep 30, 2016
BEST ANSWER: Yes, this silencer will fit with the factory pipe. You do not need to purchase a programmer to run the exhaust, but it could help you better tune the bike to perform at its best.
do you have to rejet the carb after in stall? 2001 scrambler 500
A shopper on Sep 22, 2016
BEST ANSWER: There is a possibility that you will have to re-jet your machine after installing the new exhaust. There are many factors that go into jetting a machine such as elevation, temperature, and modifications to the machine. The only way to tell if it would need to be rejetted is to try the exhaust, run the machine and see how well it runs. You can then make any necessary changes to the jets to get the machine to run best.
does this connect to the power bomb header?
A shopper on Sep 10, 2016
BEST ANSWER: Yes, it does.
